Fallen — Percival Constantine

After the creation of the Earth and the birth of Man, the Presence seemingly vanished from existence. Once the angels and demons discovered that mortals possessed souls, they became locked in an endless conflict for ownership over mankind. But Gabriel, once the leader of Heaven's forces, felt humanity should be allowed to live in peace. For his transgression, he was stripped of his wings and expelled from Heaven. Now, centuries later, the wars of man have brought the world to ruin. Man's once-vaunted technology has regressed. Lance Kells, a drifting writer with no direction in his life, inadvertantly stumbles upon this war and finds himself trapped in the middle of it. As Lance tries to uncover the truth, he will encounter a host of intriguing characters, from a hard-drinking, pink-haired avatar of death to an elderly Native American mystic. During his journey, Lance will discover a method of ending a conflict as old as time, as well as a disturbing secret which links him to Gabriel.
